(*), (* *) and (a) definition as above
The diffractogram (d-spacing and relative intensity) that is obtained by the X ray data is characterized by wide reflection, occurs many shoulder shapes peak in other stronger peak.Some or all shoulder shape peaks can not be differentiated, and this occurs in the bad sample of crystallization or X ray is obviously widened because of the very little result of crystallization in the sample.If be used to obtain used different of the equipment of X-ray diffraction pattern or condition and the present invention, then also above-mentioned situation can take place.
The given X-ray powder diffraction data of this paper are by Philips APD 1700 automatic X-ray diffraction systems, and the CuK-alpha-ray that produces with the elongated focusing X-ray pipe of operating under 40KV and the 50mA condition obtains.Crooked graphite crystal by near detector makes this radiation monochromatization.Used automatic θ one is had the 0.1mm receiving port by the compensation scatter slit, collects the stepwise scan-data between 1-60 degree 2 θ.Collected data are analyzed on the DEC that has PhilipsPW 1867/87 type 3.0 softwares (Digital Equipment Corporation) Micro PDP-11/73 computer.The given X ray computer intensity of this paper is based on the height at peak.
Can think that NU-86 has new skeleton structure or topological structure, this is a feature with its X-ray diffraction pattern.The NU-86 that is " preparation " type has the listed X-ray data of table 1 basically, thereby it is different from known zeolites.
In the chemical constitution of above-mentioned definition, per 100 moles of XO 2Y 2O 3Mole number is generally 0.1-10, for example is 0.2-7.5, as per 100 moles of XO 2Y 2O 3When mole number is 0.4-6, the obvious high pure state of the easiest formation of NU-86.
This definition comprises " preparation " type NU-86 and the product that is obtained by dehydration and/or calcining and/or ion-exchange.So-called " preparation " meaning is meant product synthetic and washing, its through or without dry or dewater.Its " preparation " type NU-86 can comprise M, a kind of alkali metal cation, especially sodium and/or ammonium, and as described below when preparing by the alkylation nitrogen compound, can comprise nitrogenous organic cation or its degraded product or its precursor.This nitrogenous organic cation is Q hereinafter referred to as.
Therefore, " preparation type " zeolite NU-86 has following mole composition (representing with anhydrous state):
100XO 2: be less than or equal 10Y 2O 3: be less than or equal 100: be less than or equal 10M 2O, wherein Q is above-mentioned nitrogenous organic cation, M is basic metal and/or ammonium cation.
Though " preparation type " NU-86 and the active form NU-86 that is obtained by calcining and/or ion-exchange all contain water, the composition of above-mentioned NU-86 provides by anhydrous component.These types comprise " preparation type " NU-86, its H 2The O molar content depends on synthetic after drying and storage requirement or activation condition.The general every 100XO of the mole number of institute's water content 2Be 0-100.
Calcinated type zeolite NU-86 does not contain organic compounds containing nitrogen, or its content is less than " preparation type ", because this organic substance is removed, usually by thermal treatment, burns organism in the presence of at air, stays hydrogen ion and makes other positively charged ion.
In ion-exchange-type zeolite NU-86, ammonium (NH 4 +) type is important, because be easy to change into Hydrogen by calcining it.This Hydrogen and as described below by the containing metal pattern of ion-exchange introducing.In some cases, zeolite of the present invention is exposed to that the result can partially or completely remove backbone element such as aluminium and generate Hydrogen in the acid.This just provides and changed the method that zeolitic material is formed behind zeolite synthesis.
The present invention also provides the method for preparing zeolite NU-86, and it comprises makes a kind of aqueous mixture reaction, and this mixture contains at least a oxide compound XO 2The source, at least a oxide compound Y 2O 3The source, optional at least a oxide M 2The source of O and at least a nitrogenous organic cation Q or its precursor.This mixture preferably has following mole and forms:
XO 2/ Y 2O 3Be at least 10, more preferably 10-60 is preferably 15-50;
(R 1/ n) oH/XO 2Be 0.01-2, more preferably 0.05-1 is preferably 0.10-0.75;
